lho rim body l. is n nieto] strip normallyvv forming' n eireulnr ring` zo; Shown in solid lines in ligfjl und having); ohliqne ends '13. 53, joined hy n diagonal hip und vonnw'ted hy n toggle lioint lever l. f'uh'riunod to the inner side of the outer hip-ond t2, hy u pin 5 ond .to the inner side of the inner lopend 3. by n pin t5. y

'ihe pin ."'r is carried by on eye l.. on the inner hice of n hearing' strop 8, that is lined h): suitable nienns :isi the rivets 9, to the inner 'foce oiB the outer lop-end @nid hearing' edge sind, strap are accommodated in zi slot i0, when the joint closed, and is connected to the lever hy eyes il. formed :it the end thereof. l

'ihe Slot l0, extends along the inner loo end, ond the lever i ext/ends therethrough when the deinonntoble rim is contirncted. rllhe eyes 'a' zind il, nre adopted to nnss through the end ot the slot l0 in the oper* ation ot' expanding and contracting the. rim.

ihe pin (i in Supported by two heairlinge l2 on opposite sides ot the slot :it ai. distance from the inner lap-end 3, and the leven is teiniin'ced hy o bulge or boss l5 adapted to fit and close the slot when the dexnountnhle rnn ijn expended :is in'tlig. 3.

\ From the lever li: ondiheyond the bulge oir hose v'lo extends n handle o, which conf formi to the eoneovitjr ol the inner side of the middle port of the riln while the onter side iol: the bulge or hose conforms to the oonroxity of the Asinne part when the rim is expanded oi' ('losed. The bulge or hoes 15 snugliy tite in the opening' bounded hy the unslotted, end ot the rim... the prongs or eide walls of the slot l0 and the end Woll thereof opposite to the unelotted end. so that, :is the hulpje. or hoes in tightly held in said. openi.f1; hjr the reeilienoyvof the rino, it pro vente loten-nl displacement ot' the rini ends :und I znnhnlso vonnterncts; longihndinull .cmnprossion :ind displacement there t. thus ooptrntingr with thonnnal 1'inz;,ec1.1ring; ineens. not shown, in order to tittninfperiieot alignment o't the rim ends.

When the rim nnd the tire are mounted upon :i wheoh ns is 'tragmentnlll shown in. Fig. I. the hoseietnrt-herheld nod securely looked into plm-e hy Ine-nhs ot the lever hundlo u.. which then rents against the follylmnd iT in n oirvumterenthil direi-tion he hij vond the hose l5 or the opening' in the rim.

ln the lever Shown. the terminal oyes li nro foi-med in n bifurcation :it one end'o'f the thickened port oiE the ierer. and the handle rf is formed at the other end of Sm'h {hhhoned pzu't` while the intein'lediate pintle eye or sont 1&3 ol' the lever in formed opposite to the hose i5. The lever thus constructed forms an accessory that together with the parts 7 and 12, the pintles and the i rivets mayI be used to transfornila-rim of the usual construction intothe improved deinountable rim disclosed.

The pin (3 is mounted in the e e 1G, that projects from the inner tace of t e lever in contormity with 'the projections formed by the eyes 7, t1, and l2; and the telly band li" and telly 18 of the Wheel are recessed as `at 19 to accommodate such' inner projections.

This prevents rim creeping.

in practice. to release the rim from the tire 20. the lever 4 will be thrown in as indicated in dotted line in Fig. 1 and in solid lines in Fig. 2. A reversed movement of the lever again tightens the rim in the tire, and it may thus be mounted on the wheel as indicated in Figs. 3 and 5.

By lapping the abutting or adjacent ends in which the ring terminates as shown, the closing ot' the lever brings the parts to a certain stop; but it is understood that the invention is not limited to lapping the ends although such construction is at present preferred.

Nor do .l limit the construction to slotting onlyY one of the ends; as various construction and n'ioditications not necessary to be shown, will be understood by the constructor, it being provided that such construction and moditications be within the limitot my claims.

l claim:

1'. The combination with a demountable tire rini in the forni ot' an open ring havintar one end thereof slotted so that. when the rim is expanded, an opening is formed which is bounded by the unslotted end of the rim, the prongs on the sides ot' the slot and the end wall opposite to the unslotted end, ot' a, lever adapted to expand or tocontract the rim and having?r on its outsidea boss adapted to snugly fit said opening, said lever being pivotally seated adjacent to the unslotted end of the rim and also being pivotally seated opposite to said boss, so that, when the rim is expanded the boss is tightly held in said opening and thus constitutes means that aids in preventing lateral and longitudinal displacement ot' the rim ends.

rlhe combination with a demountable tire rim in the form ot an open ringl havingy one end thereof slotted so that. when the run is expanded, an opening is formed which is 55 bounded by the unslotted end of thc rim., the prongs on the sides of the slot and the, end wall opposite to the unslotted end, of ai lever adapted to expand or to contract thci rim and having on its outside a boss adapted to snugly tit said opening; and a handle cxtending circuinferentially vtroni said lever beyond said boss and opening and conorining to the concavity ot' the inside o the rim when the rim is expanded. said leverbeing pivotally Seated adjacent to the unslottcd end of the riin and also being pivotally seated opposite to said boss` so that, when the rim is expanded, the boss is tightly held in said opening and thus constitutes means that aids in preventing lateral and longitudinal displacement ot' the rim ends.

3. The combination with a dcinountahlc tire rim in the torni of an open ring having one end thereof slotted so that, whcn thc rim is expanded an opening" is formed which is bounded by the unslotted end of the rim. thc prongs on the sides of the slot and the end wall opposite to the unslottcd end. ol' a lever adapted to expand or to contract the riin and having on its outside a boss adapted to snugly' tit said opening; and a handle cxtending circumfeientially from said lever beyond said boss and opening and contornin ing' to the concavity of the inside ol thc riui `.vhile theboss is with its outer face contorniing to the convexity ot' the outer tace ol' the rim when the rini is expanded. said lever being pivotally seated adjacent to thc unslotted end ot' the rim and also beineY pivotally seated opposite to said boss. so that. when the rim is expanded, the boss is tightly held in said opening and thus constitutes means that aids in preventing lateral and longitudinal displacement of the rini ends and also means at the. rim cnds tor prevent` ing injury to thc tire on said riin.

In testimony whereof. l have hereunto set my hand at Los ngeles California. this 12th day of September. 1918.
